Boto3 Retrier Configuration¶
Prowler's AWS Provider uses the Boto3 Standard retry mode to assist in retrying client calls to AWS services when these kinds of errors or exceptions are experienced. This mode includes the following behaviours:
- A default value of 3 for maximum retry attempts. This can be overwritten with the
--aws-retries-max-attempts 5 argument.
- Retry attempts for an expanded list of errors/exceptions:
- Retry attempts on nondescriptive, transient error codes. Specifically, these HTTP status codes: 500, 502, 503, 504.
# Transient errors/exceptions RequestTimeout RequestTimeoutException PriorRequestNotComplete ConnectionError HTTPClientError # Service-side throttling/limit errors and exceptions Throttling ThrottlingException ThrottledException RequestThrottledException TooManyRequestsException ProvisionedThroughputExceededException TransactionInProgressException RequestLimitExceeded BandwidthLimitExceeded LimitExceededException RequestThrottled SlowDown EC2ThrottledException
- Any retry attempt will include an exponential backoff by a base factor of 2 for a maximum backoff time of 20 seconds.
